Spencer has now teased that the episode "is not going to be the happiest thing in the world" but will be "an appropriately satisfying ending for longtime viewers".

Spencer declined to elaborate on Chase's reunion with ex-wife and former colleague Cameron (Jennifer Morrison) in 'Everybody Dies', only telling TV Line that the character "has a final moment which I'm very, very happy that they approached".

As well as Spencer and Morrison, former House cast members Olivia Wilde (Thirteen), Amber Tamblyn (Masters) and Kal Penn (Kutner) will also return for the finale.

House's last episode airs next Monday (May 21) at 9/8c on Fox. In the UK it airs Thursday, May 24 at 10pm on Sky1.
